OH and if that oil filter isn't a Fleetguard and contains an o-ring where it threads on. There could be very well be a piece of it somewhere blocking an oil passage causing a drop in pressure and trashing a bearing..

We have tried Fleetguards with no change in the past. Even tried their extended service filter with the same issues. This truck had issues with the factory crank. There is an issue somewhere.
